| Field Summary | |
| protected int | m_count
optional message count for the FIFO. | | protected long | m_rsize
optional number of bytes read from FIFO. | | protected long | m_wsize
optional number of bytes written - but not to the FIFO. |
| Constructor Summary | |
| public | Fifo()
Default c'tor: Construct a hollow shell and allow further
information to be added later. | | public | Fifo(String filename, int descriptor)
Constructs a FIFO object.
Parameters:
filename - is the name of the file that stat was invoked
Parameters:
descriptor - is a valid file descriptor number. |
| m_count | | protected int m_count(Code) | | optional message count for the FIFO.
|
| m_rsize | | protected long m_rsize(Code) | | optional number of bytes read from FIFO.
|
| m_wsize | | protected long m_wsize(Code) | | optional number of bytes written - but not to the FIFO. This
has to do with the message size that was created from the
original input message.

| Fifo | | public Fifo()(Code) | | Default c'tor: Construct a hollow shell and allow further
information to be added later.
|
| Fifo | | public Fifo(String filename, int descriptor)(Code) | | Constructs a FIFO object.
Parameters:
filename - is the name of the file that stat was invoked
Parameters:
descriptor - is a valid file descriptor number. |
| toXML | | public void toXML(Writer stream, String indent, String namespace) throws IOException(Code) | | Dump the state of the current element as XML output. This function
traverses all sibling classes as necessary, and converts the data
into pretty-printed XML output. The stream interface should be able
to handle large output efficiently.
Parameters:
stream - is a stream opened and ready for writing. This can alsobe a string stream for efficient output.
Parameters:
indent - is a String of spaces used for prettyprinting. The initial amount of spaces should be an empty string.The parameter is used internally for the recursive traversal.If a null value is specified, no indentation norlinefeeds will be generated.
Parameters:
namespace - is the XML schema namespace prefix. If neitherempty nor null, each element will be prefixed with this prefix,and the root element will map the XML namespace.
exception:
IOException - if something fishy happens to the stream. |
